Hi There, I have a brand new 2009 WR450 that I scooped up. I've ridden 2-strokes my entire life and this is my first 4-stroke, Ever! I'm excited. Havent ridden it yet but I did just put on the AIS block off, throttle stop & JD Jet Kid (168 Main, Stock Pilot, Red needle 4th clip, fuel screw 1 1/2 out.. I'm at Sea Level). Fired right up and idles fine. HOWEVER..... I've noticed that within 1 min at idle the pipe is red hot and so is the radiator and cylinder. Now I've always been on a 2-stroke and it takes a long time at idle to warm things up... is this normal on a 4-stroke? Also.. off topic but on the AIS blockoff is there supposed to be a gasket or anything between that machined plate and cylinder? Thanks in advance!
